PCB for OpenMQTTGateway as RF to MQTT Bridge for Home Assistant.


Parts:

SRX/STX 882: https://amzn.to/3lJkpYt *

NodeMCU: https://amzn.to/3nONsLR *

Terminal-Block: https://amzn.to/373swuE *



Receiver (SRX 882) on D7

Transmitter (STX 882) on RX


Firmware: https://github.com/1technophile/OpenMQTTGateway

Use Source Code (zip) on release page.


Following changes in sourcecode needed:


uncomment following lines in "User_config.h"

#define ZgatewayRF     "RF"       //ESP8266, Arduino, ESP32
#define ZmqttDiscovery "HADiscovery"//ESP8266, Arduino, ESP32, Sonoff RF Bridge


Change the Port of receiver by change line in "config_RF.h" as seen below.

from:

#  define RF_RECEIVER_GPIO 0 // D3 on nodemcu // put 4 with rf bridge direct mod


to:

#  define RF_RECEIVER_GPIO 13 // D7 on nodemcu


Upload the modified Sketch to your NodeMCU. After upload and restart the device should appear in Home Assistant.

If you send any 433MHz signal with any transmitter, this signal should appear as new Device in HA, too if autodiscover is enabled for MQTT in HA.
